As a spokesperson for Case-Shiller said, values “crept forward” in July. But not that it matters — the Case-Shiller Index is a better tool for economists than it is for homeowners in Edmond. This is for 3 reasons.

First, the Case-Shiller Index is on a 60-day delay but real estate sales are based on prices today. A lot can change in 60 days, and it often does. Therefore, the Case-Shiller Index is a better snapshot of the former market than the current one.

Second, the Case-Shiller Index is geographically-limited. It tracks just 20 cities, ignoring some of the largest metropolitan areas in the country including Houston, Philadelphia, and San Jose. Smaller cities like Tampa are included.

And, lastly, national real estate data remains somewhat useless anyway. All real estate is local, rendering citywide statistics too broad to have any real meaning to an individual. To find out what’s happening on a neighborhood-by-neighborhood level, you can’t look to a national survey — you have to look to a local real estate agent instead.
